CLOSURE FoR OIL-CUPS...

SPEOTFICATION forming part of Letters Patent No. 635,717, dated October24, 189d. Application filed February 4:, 1899. Serial No. 704,573. (Nomodel.)

T0 alt whom it may concern.-

Be it known that we, GEORGE W. EMERIOK and WILLIAM J. EMERICK, citizensof the United States, residing at Montandon, in the county ofNorthumberland and State of Pennsylvania, have invented certain new anduseful Improvements in Closures for Oil-Cups, of which the following isa specification.

The object of our invention is to provide an improved closure or cap foroil-cups used upon engines, locomotive or stationary, or whereveravailable.

The nature of our invention 'will be described below and pointed out inthe claims.

In the drawings, Figure 1 is a perspective view of an oil-cup embodyingour invention. Fig. 2 is a vertical section. Fig. 3 is a detail View ofthe cap removed. Fig. 4: is a plan view, all parts but the cylinderremoved. Fig. 5 is a detail in vertical sectionat right angles to Fig.2. Fig. 6 is a detail of the key.-

Like letters refer to like parts.

A represents the oil-cup.

B is the outlet-nipple at the bottom, which may be exteriorlyscrew-threaded to make any suitable connection.

0 is a yoke or seat, and in this may be ad- 3' usted a screw-threadedcone-valve D for closing the outlet or regulating the flow of oil. Thisvalve is held to the desired adjustment by a nut E, resting upon the topof the yoke.

At the top of the cup are interior inclined flanges a, separated byinclined recesses cl.

F is the cover, having on its inner face a circular groove f to rest onthe outer end of the cup and opposite lugs h, with inclined sidesadapted to enter recesses d and hold the cap from turning while the keyH is being turned upon inclined flanges cor at any time. Recesses 01also permit the insertion of the key-head, here shown as elliptical inshape.

K is a washer.

M is the key-shank passing through the cover, and N is a nut orsquare-shaped handle attached to said shank, which is turnedindependently of the cover, although the key and cover are joinedtogether by said nut.

The operation is briefly thus: Bring the head of the key andlugs h inline andinsert them into recesses d. The cap and the circular dependingflange or rim of the cap formed by groove f on the under side willextend somewhat below the top of the cup. Now turn the key to the right,when the key head will move along the inclined surface of the flanges c,and the further the key is turned the tighter it will lock and draw downthe cap. To remove the cap, turn the key to the left until the ends ofthe key-head register with recesses d, when the key and cap may beeasily taken out. The construction is simple and effective. The oilcannot escape at the top of the cup, yet the cover can be quicklyinserted or removed.

Having described our invention, what we claim, and desire to secure byLetters Patent, 1s

1. The'combination with the cup having at the top interior, inclinedflanges separated by inclined recesses, of a cap provided on its innerface with a circular groove and lugs, and a key turning independently ofthe cap and lockin g with said flanges, as set forth.

2. The combination with the cup having at the top interior, inclinedflanges separated by inclined recesses, of a cap provided on its innerface with a circular groove forming a depending flange and with oppositelugs, and an independently-turning key held to the cap by a nut orhandle on the key-shank, as set forth.

In testimony whereof we afflx our signatures in presence of twowitnesses.

GEORGE W. EMERICK. WILLIAM J. EMERIOK.
